Contact system and locking
The 350433-4 is the 12-circuit member of TE's Universal MATE-N-LOK header line, a shrouded 4-wall through-hole header with a locking ramp for positive retention against vibration.
Pitch and row layout
Three rows at 0.250" (6.35mm) pitch, with the same 0.250" (6.35mm) row spacing — the 12 positions are loaded fully across the three rows, giving a 4-per-row layout.
